App field reference
Complete list of every App spec field. Required fields are marked.
“Applies to” notes workload-type scoping where relevant; most fields apply to
all types. For task-oriented usage see
The App claim and
Data services.
Provenance. The App XRD and composition are not in this repository —
they live in
Smana/crossplane-configuration,
which this repo pins as a Configuration package
(infrastructure/base/crossplane/configuration/configuration-packages.yaml,
currently ghcr.io/smana/crossplane-configuration-aws:v0.1.0). This table was
reconciled by hand against that repository’s apis/app/definition.yaml (the
CRD schema — types, enums, CEL rules) and apis/app/kcl/main.k (composition
defaults that never appear in the schema, such as resource requests/limits or
the gateway/route fallback names) at the commit tagged v0.1.0.
To regenerate: check out Smana/crossplane-configuration at the tag
currently pinned above, and read apis/app/definition.yaml +
apis/app/kcl/main.k in that checkout — there is no automated extractor, so
this page drifts from the schema the same way any hand-maintained reference
does. Re-verify after every pin bump.

Correction from the old field reference:
persistence was previously
marked “Applies to: web, worker”. That’s wrong — the Deployment and the
CronJob share the same pod-builder (_podSpec, apis/app/kcl/main.k:465,
reused by the CronJob’s job template at main.k:630), and the persistence
volume/mount are added to that shared spec unconditionally
(main.k:357-366). A cron App can mount a PVC. deploymentStrategy
still doesn’t apply to cron — that field only ever sets Deployment.spec.strategy,
which a CronJob doesn’t have.image
